No I haven't seen that.
I noticed the same problem, on Vista and XP/SP2, using freemarker-ide-1.0.0.beta3, an up-to-date eclipse 3.3 and freemarker 2.3.9
-BUT- I'm not using the outline view
I'm unable to spot when it's exactly happening. Sometimes eclipse crashes after 5 minutes and sometimes it takes hours.
Here are some observations:
When working on an FTL file, copy-paste operations and using auto-completion seem to cause crashes faster.
If i've some ftl files open but work on a Java file, there's no problem.
By monitoring Task Manager, the crash is cleary due to a GDI handle leak
As the GDI handle count is increasing, freemarker ide becomes slower until it becomes unresponsive, and then so does eclipse; unable to save or do anything else such as close a file.
I just updated to a nightly build and hope this will solve my problem :)
Hope this help to reproduce it.
we haven't changed anything in the freemarker IDE for a long time so i doubt it has gone away.
Anyone that figures out what is causing it is encouraged to open up an issue in jira about it.
